Watch Live: Secretary of State Blinken speaks at U.N. on "Russia's threat to peace and security"

Secretary of State Antony Blinken is delivering remarks at the United Nations Thursday morning on "Russia's threat to peace and security" — as the U.S. says evidence shows Russia is "moving toward an imminent" Ukraine invasion. He will be speaking at the U.N. Security Council Meeting in New York City.

"Overnight, after a series of conversations with the White House, the National Security Council, and the State Department, I asked Secretary Blinken to come speak directly to the UN Security Council on his way to Munich about the serious situation in Ukraine,"  U.S. Ambassador to the U.N. Linda Thomas-Greenfield said Thursday. 

"Our goal is to convey the gravity of the situation," she said. "The evidence on the ground is that Russia is moving toward an imminent invasion. This is a crucial moment. This morning's Council meeting should not distract us from that fact - it should focus on what is happening right now in Ukraine."
